6 Claims.

This application is a division of my copending application Serial No.731,425 filed June 20, 1934.

This invention relates to carriers as a means for adjustably supportingracks, pans and the like in cooking ranges, cabinets, refrigerators andother apparatus. It relates more particularly to adjustable carriers foruse in ovens in cooking ranges whereby the art of broiling may beperformed with greater ease, economy and accuracy.

Heretofore it has been general practice to provide a series of tieredgrooves or slideways attached to or formed in the side walls of thebroiler, the oven or the broiler drawer for supporting the pan, the rackand the like, and from which the pan, the rack and the like could be Iwithdrawn and then reinserted upward or downward as a means foradjusting the required distance from the heating unit.

The objects of my invention are: to provide a carrier device, which issimple in construction and efiicient in operation, designed to support apan, a rack or the like and to move upwardly or downwardly insubstantially horizontal position whereby the pan, the rack or the likeneed not be removed in making adjustments; to provide a carrier devicedesigned to slidably support a pan, a rack or the like which may beautomatically adjusted upwardly or downwardly by the in and outmovements of a drawer; to provide an adjustable carrier devicesupporting a pan, a rack or the like which device is compact, simple andefiicient; to provide an oven, a drawer broiler or a compartment with acarrier which may adjustably support a pan, a rack and the like andwhich may be automatically adjusted upwardly or downwardly insubstantially horizontal position by the movements of a drawer as meansfor regulating the required distance and for maintaining a centrallocation with relation to the heating unit.

A still further object consists in providing cer- Similar numerals referthroughout the several views.

Referring particularly to Figs. 1 and 2, the broiler drawer compartmentis equipped with a burner unit I6 and a drawer 14 mounted in anyconventional manner for sliding movement into and out of the drawercompartment.

The actuating mechanism concealed between the inner and outer'side wallsof the drawer broiler 14 comprises the arm 25 pivotally mounted on thebearing bolt 28 and the arm 26 pivotally mounted on the bearing bolt 21.The elliptical segment gear member 29 is freely journaled between thearms 25 and 23 on the bearing pin 30 and is contactively supported bythe support pin 3! in contact with the spirally shaped edge 32.

The pivotally mounted arms 25 and 26 which are preferably composed offlat iron are supported by the inner walls of'the drawer 14 by means ofthe bearing bolts 2! and 28. They are assembled in flatwise, crosswiseformation with oii" sets to provide freedom of action with theelliptical segment gears 29 mounted between them. A substantiallyhorizontal movement is maintained in the up and down travel at thetraveling ends of the arms 25 and 25 by means of the center bearing pin33. The bearing pin 30 is held securely in arm 25 and is slidable in theslot 39 of the arm 25.

The carriers 45! which are preferably composed of sheet iron and formedsubstantially into the shape of a channel are positioned horizontally onthe exposed inside walls of the drawer and slidably support the pan 4|including the rack to similar parts 42 upon which food may be placed forbroiling.

Inthis instance the carriers 40 are provided with welded cleat supports43 which are projected through the slots 44 of the inner side walls. Thecleat supports 43 slidably engage the traveling ends of the arms 25 and26 within the concealed space in the walls.

One of the freely journaled eccentrically designed segment gears 29 issupported adjacent each of the inner side walls of the drawer by meansof the support pins 3| and each is constructed so that the properlyspaced and irregularly shaped toothed projections 48 may engage with theactuating members 33. As rotation proceeds in either direction theadjacent teeth upon rising lift the actuating members 33 and completelydisengage them from the gears 29 effecting a precise limit in fractionalrotation and a corresponding limit in the upward or downward travel ofthe carriers 40.

The spirally shaped edge-32 in contact with the support pin 3| isinterrelated with the companion edge 45 and each is provided with aplurality of cooperating integral members 46 and 41 respectively. Thelocation of the members 45 and 41 is geometrically determined from thespacing of the toothed projections 43 and coincides with the limit infractional rotation in each phase of adjustment. The integral members 45and 41 contactively interlock with the support pin 3| holding thecarrier slideway All in position until released for readjustment.

The actuating members 33 are preferably formed of sheet iron in aninverted U shape and slidably rest upon the elliptical segment gears 29with the sides downward to maintain their position upon the gears 29.The actuating members 33 are provided with openings 3 and 35 which arerelatively located and dimensioned for contactive intermittentengagement with the toothed projections 43.

Fig. 1 represents the drawer compartment 65 and the drawer 14 which isequipped with the carrier device and operated by the in and outmovements of the drawer 14. The operating 1evers 75 are pivotallymounted on the bearing bolts 28 and supportably connect with theactuating members 33 through bearing pins '16. The projecting end of theoperating lever l5 operatively contacts with the stationary U tracks 16'secured to the bottom 11 of the drawer compartment G5, The tracks 16 areprovided with the openings T8 and 18, the raised elements 2'9 and thestops 83. The opening 18 receives the projected end of the operatinglever 15 as the drawer M is in the approximately closed position.

Opening of the drawer from the closed or the approximately closedposition causes the lower end of the operating lever 15 to engage theedge of the opening :8 in the channeled track 16' and serves to rock thelever 15 about the bearing bolt 28 as a pivot whereby the actuatingmember 33 connected to the upper end of the lever 15 is moved to theleft as seen in Fig. 1. The edge of the slot 3% in the actuating member33 is thus caused to engage one of the teeth 48 on the segment or gear29 and the gear is rotated one step in a counter-clockwise direction. Inthis way the outward movement of the drawer actuates the mechanismthrough one phase of the adjustment range and each repeated openingeffects one more adjustment. When opening the drawer half way or morethe operating levers 15 are pulled out of the openings 18 and along theslidewa-y over the projections 19 to engage the openings 18'. Closingthe drawer 14 from the approximate half open or the full open positionsreverses the adjustment of the carrier which supports the pan, the rackor the like. The mechanism automatically disengages when the maximumadjustments upward or downward are reached. The operating levers 15engage the bearings 23 by means of the slots 8| which allow up and downmovements to the levers I5 and which support the tension springs 82. Thedownward tension of the springs 82 on the levers l5 ensure theengagement of the lower end of the lever with the slot 18 or 18'.

While one form of construction of a carrier supporting mechanism whichis actuated by the in and out movements of a drawer has been describedother forms and arrangements may be used. As shown in Fig. 3 thefixtures 92 which are permanently located on the rear wall 93 of thecompartment 65 and the links 94 which pass through openings located inthe rear of the drawer 14 provide means by which the actuators 33 may bepivotally connected with the compartment 65. In this form ofconstruction the pivotally anchored actuators 33 freely engage therotatable mechanism to effect the upward and downward adjustment of thecarriers 40 through the in and out movements of the drawer 14.

Without undue complication of parts the device has been constructed inorder that its several parts may be supported by the walls, one on eachside, in the oven, 2. drawer broiler, a drawer or a compartment. Alsothe device may be mounted on sheet metal of prescribed shape and sizemade up as a unit and conveniently applied to new apparatus or suppliedas an improved feature for apparatus already in use.

Although the combined movements of pivotally arranged links and offreely journaled eccentrics are shown, other means may be adapted foractuating pivotal links and other movement combinations may be appliedto effect the upward and downward travel and the support of a pair or ofsets of carrier devices.
